To all whom it may concern: v

it lrnown that I, HERMAN A, DAVEN- ronr, citizen of the United States, residing at llroclrton, in the county of Plymouth and State of lllassachusetts, have invented certain new and useful Improvements in Sole- Pressing Machines; and I do hereby declare-the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

present invention. relates to sole pressing: machines and more particularlyto machines of this type which are employed for laying an outer sole upon a lasted shoe. With the present type of shoe supporting jack employed in this machine the shoe is supported at the toe by a pivoted rest faced with yielding material and curved to approximate the transverse curvature of the shoe. When toe rest is seated between the tip of the toe and the instep, but as the size of the shoes opera ted upon varies constantly, the toe rest must be trequentl adjusted to secure this proper positioning of a shoe. The tendency e last pin is to force the shoe into eng omeut with the toe post with a pressure sul'licient to prevent the proper adjustment of the toe rest when the-toe of the shoe is bearing upon the rest. In order to accomplish ti adjustment,therefore, it is necessary to remove the too from engagement with the rest during the relative adjustment of the toe and heel posts, the toe is next allowed to engage with the toe rest, and if not seated properly the operations must then be repeated. it will be obvious to those skilled in the art that this method of acking'the shoe entails more or less time and skill upon the part of the operator.

The object of the present invention is to provide an improved form of shoe supporting jaclc for a sole pressin machine which supports the shoe firmly during the opera tion of the machine without causing undue strains in the last and which may be adjusted with facility to position the shoe in to the pressing pad without abrading or otherwise injuring the h per. j

l Vith this object in view the various fea tures of the invention consist in certain novel features of construction, combinathe shoe is properly jacked this tions, and arrangements of parts hereinafter described and claimed, the advantages of which will be. obvious to those skilled in the art from the following description.

In the accompanying drawings illustrating the preferred form of the invention; Figure 1 represents an elevation of a portion of a sole laying machine with the present improvements embodied therein; and. F 1g. 2 1s a"deta1l showlngan elevation of the toe supporting arm and roll journaled therein.

The illustrated tion is shown in connection with a sole laying machine of the usual type comprising a sectional pressing pad indicated at l and a head 2 carrying a heel post land a toe post 5. The heel and toe posts are slidingly supported upon the head 2 in the usual manner and are provided with connections which are actuated by the hand wheel 6 to move the posts toward and fromone another. The heel post has a last pin 7 fulcrumed thereon which is normally actuated by a spring 8 to move the shoe into engagement with the toe post. This construction of the shoe supporting jack is well-known in the art and is fully disclosed in patent to Coupal, No. 353,251, dated November 23, 1886.

In the present improved construction the shoe is supported at the too by a roll which is journaled freely upon the end of the toepost in order that it may roll over the upper of the shoe as the latter is adjusted to position. it upon the jack. This roll does not abradc or otherwise damage the upper if moved thereover and furthermore, if the roll is not seated accurately with relation to the shoe it will automatically find-the lowest portion of the last when pressure is applied to the shoe. In the simplest and most effi embodiment of the invenpressing pad of the usual form it will be of the pressing pad and sh'oe.sole' score .or marthe upper as the roll wears.

In using the roll in connection withlthe noted from .an inspection of ,Fig. 1 that the shank of the pressing pad is p'rovided w th raised port ons to secure an 1ncreased.pres' sure at thls point and when pressure. is ap pliedftothe shoe sole if the:shoe is not properly centered With relation to the form the raised portions upon theshanlr of the pressing pad tend to cause a "sl-ightjbodily' .The toe post 5 isprovided with a forkedout'erend 10 havin a shaft 11 secured therein upon which a re 12 1s loosely journaled.

. This roll is provided with a metallic bushtively hard rubber,

ing 14 which surrounds the shaft andfforms a bearing for the roll, a core 15 of compa aan an 'o temsurfaoe layer 16 of soft' rubber: vulcanizedlto'the core. The outer surface layer is'concavcd to conform substantially to the: transverse curvature of the shoe and with this c'on-' struction practicallya line contact is'formed between the roll and shoe. The formation ofthe roll of hard and soft rubber enables the upper" of a shoe tobe engaged bya' soft yielding surface whereas the hard rubber core furnishes a firm support for the outer layer and serves to securely bind this layer to the metallic bushing.

While it is preferred to employth'e construction and arrangement of parts shown and described, it will be understood that this construction" and arrangement is not essential except so far. as specified in the claims,.and may be changed or modified without departing from the broader features of the invention.
